RESUMO
The present study was conducted on 40 male and 10 female students appearing for the 1st MBBS examination. Two readings of pulse rate, blood pressure and electro cardiogram were taken viz 6 months (control) and 10 minutes prior to the examination. A significant increase was seen in the pulse rate and blood pressure readings before the examination as compared to the control readings. However, no significant change was observed in electro cardiographic recordings.

Cardiovascular responses viz. systolic and diastolic blood pressure and pulse rate were evaluated in 21 females following muscular exercises for abdominal wall strengthening. Trunk curl exercise and leg raising exercise were selected for this purpose. A significant increase in systolic and diastolic blood pressure and pulse rate was observed following these exercises. These raised values returned to pretreatment value 6 min later after supine lying. These changes indicate that the need for strict supervision during sessions, especially for the hypertensive patients.

Autonomic functions were studied in female healthy human subjects during the pre-menstrual, menstrual and post-menstrual phases. Our findings indicate a higher BP (systolic) and lower GSR in pre-menstrual phase as compared to other phases. Parasympathetic activity on the other hand does not show significant differences.

Cardiopulmonary efficiency was studied in 18 Indian medical students and 19 state level athletes by estimating maximal oxygen uptake (VO2 max), and other parameters related to oxygen transport i.e., heart rate, O2 pulse, respiratory quotient, ventilation volume, breathing reserve and dysponoeic index, following graded exercise on a treadmill. Higher VO2 max observed in athletes, was due to higher stroke volume and arterio-venous O2 difference. Though athletes had higher breathing reserve at VO2 max work load, their dysponoeic index and ventilation volume at VO2 max did not differ significantly from non-athletes suggesting that athletes were economical in expending energy for work of breathing during exercise.
